An honest comparison for Shopify merchants.
You're paying $99 to $500+ per month for product recommendations but are they actually personalized? Here's a transparent, side-by-side comparison so you can decide what's right for your store.
Same category, a fraction of the price.
This is where the biggest difference shows up, and often the reason merchants start searching for a Rebuy alternative in the first place.
$99 – $999+/month
Tiered by orders per month. Starter plan at $98 (up to 250 orders), scaling on your order count. Premium support adds $499/month. Platform One bundle ~$598/month(upto 500 orders).
Free to $449/mo: published flat plans
Start free with AI recommendations; AI Search comes with every paid plan. Paid plans are flat: $39 to $449/month, billed through Shopify, with no usage fees on any plan. High-volume stores step up to Pro or Scale; the bill never moves on its own. No negotiations, no surprises.
Rules vs. bespoke AI.
Rebuy's recommendations tend to be broad: “customers also bought” and collaborative filtering. PersonalizerAI builds bespoke models for each merchant.
Rebuy's approach
- Rule-based + AI recommendations
- General patterns: “customers also bought”
- Requires manual merchandising rules
- Complex setup and constant tuning
PersonalizerAI's approach
- ✓Bespoke AI models trained on YOUR catalog
- ✓Understands product relationships and nuances
- ✓Runs on autopilot with rules optional
- ✓23-34% AOV lifts from real catalog intelligence
- ✓Models trained on your store's data only, never pooled across merchants
The full comparison.
Smart Cart. Rebuy's Smart Cart is a standout: a fully customizable cart drawer with tiered progress bars, gift-with-purchase logic, and subscription prompts.
Recommendation depth, AI search quality, price at every order volume, setup speed, and included support. Our models are trained specifically for your store.
How do you know it’s working?
Revenue counts only when a shopper clicks a PersonalizerAI widget or search result and then buys.
auditable order by orderRebuy tracks widget interactions and attributes downstream purchases, which can include orders that would have happened regardless, inflating apparent ROI. PersonalizerAI takes credit only for revenue a shopper clicked its way into — nothing more.
No view-through credit · same session, click to add-to-cart · Shopify is the source of truth
The feature most merchants overlook.
Up to 30% of ecommerce visitors use site search, and those visitors convert at 2–3x the rate of browsers.
Natural language
When a customer types "blue dress for summer wedding," our search understands intent, not just keywords.
Fewer zero-results
AI understands synonyms, product relationships, and catalog structure to always surface relevant results.
Higher conversion
Higher search conversion rates for stores with large or complex catalogs. Included from the $39 Starter plan.
Setup and ongoing management.
Complex. Setting up effective recommendation rules, configuring the Smart Cart, creating A/B tests, and managing merchandising logic requires time and expertise. Many merchants spend hours per week tweaking rules.
~30 minutes from install to live recommendations and search. No merchandising rules required (they're there on Growth+ when you want control), no manual widget configuration. The models improve continuously as they process more data. Runs on autopilot.
